I have just come into 2 large bags of postcard which range from the 1940 through to the 1980s. They appear to be every postcard my Grandmother and Aunt received and bought during that period, they extensively travelled in Europe in the 50s and 60s and there is a mixture of written/post marked cards and blanks... I have started sorting through them, but looking for some guidance on what is the best way to see what they are worth. There are a few thousand:)

Should have added I'm based in the North East of Scotland

Probably not a great deal, as the market for cards of this era is much smaller than for those of a century ago. I suspect that there aren't many postcard fairs in your part of the world; the usual advice is to visit one and see what the dealers there say.
